Metabolite diversity of Microcystis strains shows tight correspondence to genotype and may contribute to ecotype specificities.

ABSTRACT: Microcystis is one of the most common bloom-forming cyanobacteria colonizing freshwater ecosystems worldwide. This genus remarkably produces numerous bio-active accessory metabolites, which are believed to be potentially involved in different ecological and/or physiological processes. However, their genuine contribution to the evolutionary success of Microcystis blooms remains undetermined. To better depict the potential relationship between the local genetic diversity of blooming Microcystis populations and their respective associated chemical diversity, we conducted a joint genomic and metabolomic analysis of 65 Microcystis strains collected from various lakes in France and surrounding Western European countries. Interestingly, both core and pan-gene phylogenetic analysis place 57 of the
